RESUMO
INTRODUCTION: Among children who suffer from acute recurrent pancreatitis (ARP) or chronic pancreatitis (CP), acute pancreatitis (AP) episodes are painful, often require hospitalization, and contribute to disease complications and progression. Despite this recognition, there are currently no interventions to prevent AP episodes. In this retrospective cohort study, we assessed the impact of pancreatic enzyme therapy (PERT) use on clinical outcomes among children with pancreatic-sufficient ARP or CP. METHODS: Children with pancreatic-sufficient ARP or CP in the INSPPIRE-2 cohort were included. Clinical outcomes were compared for those receiving vs not receiving PERT, as well as frequency of AP before and after PERT. Logistic regression was used to study the association between development of AP episodes after starting PERT and response predictors. RESULTS: Among 356 pancreatic-sufficient participants, 270 (76%) had ARP, and 60 (17%) received PERT. Among those on PERT, 42% did not have a subsequent AP episode, during a mean 2.1 years of follow-up. Children with a SPINK1 mutation ( P = 0.005) and those with ARP (compared with CP, P = 0.008) were less likely to have an AP episode after starting PERT. After initiation of PERT, the mean AP annual incidence rate decreased from 3.14 down to 0.71 ( P < 0.001). DISCUSSION: In a retrospective analysis, use of PERT was associated with a reduction in the incidence rate of AP among children with pancreatic-sufficient ARP or CP. These results support the need for a clinical trial to evaluate the efficacy of PERT to improve clinical outcomes among children with ARP or CP.
RESUMO
PURPOSE OF REVIEW: Pediatric acute pancreatitis is an infrequent but potentially serious condition in children. Most have mild cases with spontaneous resolution, but up to one-third of patients can have moderate or severe disease or progress to recurrent or chronic pancreatitis. RECENT FINDINGS: Significant advances have been made in the field of pediatric pancreatology with a recognition that pediatric acute pancreatitis can vary significantly from adult disease with different risk factors and outcomes. There is better understanding of appropriate management for pediatric pancreatitis as well as growing literature in complications of pancreatitis. SUMMARY: The most common risk factors for pediatric acute pancreatitis include biliary disease, drug/toxin and idiopathic. Management involves adequate fluid resuscitation, early enteral nutrition and appropriate pain control. Systemic and local complications, including SIRS, necrosis and fluid collections, can occur in up to one-third of patients and care is largely supportive with a careful step-up approach to fluid collections and necrosis.
